Hi,
I started a topic yesterday (now closed) about calling the Merge Users plugin programmatically, and Rafael kindly referred me to the release notes, which feature a mention of the plugin now having a UI ([Discourse 2.5.0.beta3 Release Notes](https://meta.discourse.org/t/discourse-2-5-0-beta3-release-notes/148766)). Sadly, my skills with the Discourse API are not such that I can translate this into an API call. This is something that we will need to do from our application on a fairly regular basis. Can you help me out, please?
Thanks in advance,
Mark Pemburn

The button is visible at the bottom of a user’s administration page.
If you open your [browser developer tools while using it](https://meta.discourse.org/t/how-to-reverse-engineer-the-discourse-api/20576), you will see the request that needs to be made.

Hi Kane,
Thanks for the tip! It took me a while to be able to create some users in my sandbox Discourse, but I was able to do so today. I took what I gleaned from the dev tools Network panel and attempted to duplicate it via Postman. These are the values:
Method: POST
Endpoint: [https://my-discourse-sandbox/admin/users/](https://my-discourse-sandbox/admin/users/){source user ID}/merge.json
Headers:
```plaintext
Content-Type: multipart/form-data
Accept: application/json
```
Params:
```plaintext
Api-Key: {create via the UI}
Api-Username: system
context: /admin/users/{source user ID/{source username}
target_username: {target username}
```
The response was:
```plaintext
{
"errors": [
"The requested URL or resource could not be found."
],
"error_type": "not_found"
}
```
Any idea of what I’m doing wrong?

Those all look correct at a glance. Have you checked that the target\_username value exists?

Kane,
Yes, both source and target are current users. If I remove the headers, I get back an HTML page that says “Oops! That page doesn’t exist or is private.” The “page doesn’t exist” part is understandable for a 404 error, but I’m not sure what “private” implies here.

@mpemburn did you have any success with this?
I’m migrating some mailing lists to a discourse instance. Since many people used different emails the transfer creates many staged users per real person. I would like to automate the merging of users via the API.
